A new federal study warns a major tailings spill at Alaska’s proposed Donlin Gold mine could devastate a nearby village and cause long-term environmental damage. The US Army Corps of Engineers and the Bureau of Land Management released the draft environmental impact statement, examining a scenario where 27% of the mine’s tailings capacity fails.
This scenario could bury Crooked Creek village, making it uninhabitable. Metal contamination downstream might last over a century. Fish populations in the Kuskokwim River could remain low for generations, impacting local communities and their resources.
Donlin Gold is one of the industry’s largest undeveloped gold deposits. It holds about 40 million measured and indicated ounces grading 2.22 grams gold per tonne. NOVAGOLD, which will own 100% of the project, expects to produce about 1.1 million ounces annually over a 27-year mine life.
Local groups, including the Organized Village of Kwethluk, expressed concern that the study did not examine a larger spill. They say a dam failure poses a significant risk to traditional ways of life and the environment. The US Army Corps is accepting public comments on the draft study until October 23.
